SIDING FORM Paul L. Furst, Wichita, Kans. I Application February 4,1948, Serial No. 6,215

This invention relates to forms for casting materials and particularlybuilding shapes such as wall spacing slabs or siding, where it isdesired to form a plurality of shapes of the same design, and inparticular a frame having a base adjustably mounted therein withover-lapping side bars removably and adjustably positioned thereon forforming over-lapping edges of forms cast in the frame. v

The purpose of this invention is to provide a form for mass productionof molded shapes wherein the thickness of the shapes may readily beadjusted and from which the molded shapes may readily be ejected.

In the usual forms or dies for casting materials particularly of theopen type it is difficult to form the shape with alternately positionedover-lapping flanges such as are required for siding for buildings andthe like. With this thought in mind this invention contemplates arelatively thin frame with a floating base held by adjusting screws anda superimposed frame with one side and one end fixedly mounted on theformer frame and the other side and end formed with an L- shaped frameadjustably mounted on said former frame.

The object of this invention is to provide means whereby comparativelylarge units of siding for walls of buildings may be cast economically inlarge quantities.

Another object of the invention is to provide means whereby compositionsof materials including resilient and fireproofing substances may beconverted into slabs adapted to be used for siding in buildingconstruction.

A further object of the invention is to provide a form for manufacturingsiding for buildings from compositions of materials which is of a simpleand economical construction.

With these and other objects and advantages in View the inventionconsists of the new and novel combination, construction, and arrangementof parts as hereinafter more fully described, set forth in the claimappended hereto, and disclosed in the accompanying drawings, formingpart hereof, wherein:

Figure 1 is a plan view of the form with part broken away.

Figure 2 is a view showing a side elevation of the form with part brokenaway.

Figure 3 is a view showing an end elevation of the form.

Figure 4 is a cross section through the form with part broken away,taken on line 44 of Figure 1.

1 Claim. (Cl. 25121)- H Figure'5 is a similar section showing a unit ofsiding cast therein.

- Figure 6 is also a cross section through the form taken on line 6-6 ofFigure 6.

Figure 7 is a similar section illustrating a unit of siding casttherein.

Figure 8 is a view illustrating a unit of siding cast in the formshowing the over-lapping edges.

Figure-9 is a similar view looking toward the opposite end thereof.

Referring now to the drawings wherein like reference characters indicatecorresponding parts the siding form of this invention includes an angleiron frame If), a floating'base l I, and an L-shaped superimposed framel2.

The frame I 0 is formed with vertically disposed side walls l3 and I4having horizontally positioned flanges l5 and I6, and verticallydisposed end walls I1 and I8, having horizontal flanges I9 and 20. Theend walls I! and I8 are provided with inwardly extending lugs 2| and 22and 23 and 24 respectively, and screws 25 are threaded in the lugs withthe inner ends extending upward engaging the under surface of the baseII, as shown in Figures 4 to 7, inclusive. Bars 26 are permanentlymounted on the flange 20, as by welding, and a bar 21 is similarlymounted on the flange I6.

In the design shown the base I l is formed with ridges 28 havinginclined surfaces 29 therebetween simulating siding, and this is freelypositioned on the ends of the screws 25, whereby the elevation thereofmay be readily adjusted to change the thickness of the slab of siding.The

screws 25 are also used to eject the slab of siding after the materialthereof has set, as by screwing the screws inward the base is forcedupward so that the siding may readily be removed.

The frame I2 is positioned on the flanges l5 and Hi to complete the formand the inner edges thereof extend over the inner surfaces of thevertical walls l3 and I! which provides an overlap strip 28 along thelower edge of the slab 29 and also an over-lap 30 on one side. The frameI2 is adjustably mounted on screws 3|, 3 2, and 33, that are threaded inlugs 34, 35, and 36 extending from the outer edges of the frame, and thescrews 3| and 32 are threaded in the flange l9 with the screw 33threaded in the flange l5.

With the parts arranged in this manner siding units are formed withover-laps 28 and 30 on the lower and right hand edges of the slabsillustrated in Figures 8 and 9, and under-laps or flanges 31 and 38 areformed on the upper and left hand edges respectively.

The upper surface of the base II is formed with steps and inclinedsurfaces to represent a form of siding, however, it will be understoodthat the upper surface of the base that contacts the material of whichthe siding is formed may be shaped or grooved to simulate bricks, woodblocks, tile, or siding of any type or design.

In use the base II and frame l2 are set to the desired positions and thematerial is poured and,

the upper sun'fa'ce ileveled oif. After the material has set the frameI2 is removed and the formed slab forced upward by the screws 25 whereinit may be readily removed from the form.

The slab may be formed of any suitable com? position of material andparticularly fireproofing materials, and may'also be formed of concrete,clay, and the like.

It will be understood that modifications may be made in the design ofthe form and arrangement of the parts thereof without departing from theof "the What is claimed is:

In a term for casting Minding wal l facing slabs, the combination whichcomprises a rectangular firaped iramehaving vertically disposed side andend wallswith horizontally disposed flanges extended outwardly from theupper edges and with lugs having threaded openings therein extendedinwardly from the inner surfaces thereof, a floating base with the uppersurface thereof formed with P ojections and. indentations to representthe face of siding on facing slabs cast the form, screws threaded m thelugs on the inner surfaces of the Walls of the frame upon which thefloating base of the frame is carried whereby the position of the baseis vertically adjustable, bars mounted on the flanges of the side wallsand adjoining ends walls of the frame spaced from the inner edges of thewalls thereof for providing overlapping flanges on two sides of a slabcast in the frame, an L-shaped frame positioned on the flanges of theside and end of the frame opposite to the side and end thereof on whichthe said bars are positioned with the inner edges of the L-shaped frameextended over the inner surfaces of the corresponding side and end wallsthereof for providing grooves to receive the overlapping flanges ofadjoining slabs, and screws extended through the said L shaped frame andthreaded in the flanges of the rectangular shaped frame for removablymounting the said L-shaped frame on the flanges of the rectangularshaped frame.
